SaltStack自动化安装配置haproxy的Keepalived

keepalived配置安装

什么是vrrp，阿里云不支持组播，所以阿里云上不能配置keepalived，但是它有自己的slb。
运维的大忌，在命令行复制粘贴，一般是先复制到文本中查看确认以后
salt编写配置管理keepalived之前，首先自己安装一遍

一、下载以及编译安装

wget http://www.keepalived.org/software/keepalived-1.2.19.tar.gz
tar zxf keepalived-1.2.19.tar.gz
cd keepalived-1.2.19
./configure --prefix=/usr/local/keepalived --disable-fwmark
make && make install

二、编写功能模块配置
1、创建keepalived配置管理相关目录

mkdir /srv/salt/prod/keepalived
mkdir /srv/salt/prod/leepalived/files
 
cd /usr/local/src/keepalived-1.2.19/keepalived/etc
cp init.d/keepalived.init /srv/salt/prod/keepalived/files
cp keeplived/keepalived.conf /srv/salt/prod/leepalived/files
 
keepalived文件位于编译安装后的目录下，该文件是keepalived后台运行配置文件
cp /usr/local/keepalived/etc/sysconfig/keepalived /srv/salt/prod/leepalived/files/keepalived.sysconfig
或在解压目目录下也存在该文件
cp keepalived/etc/init.d/keepalived.sysconfig /srv/salt/prod/keepalived/files/
cp /usr/local/src/keepalived-1.2.19.tar.gz /srv/salt/prod/leepalived/files/

2、修改启动脚本

cd /srv/salt/prod/keepalived/files
vim keeplived.init

daemon keeplived ${KEEPALIVED_OPTIONS}修改为
daemon /usr/local/keepalived/sbin/keepalived ${KEEPALIVED_OPTIONS}

3、keepalived安装配置install.sls
cd /srv/salt/prod/keepalived
vim install.sls

include:
  - pkg.pkg-init
keepalived-install:
  file.managed:
    - name: /usr/local/src/keepalived-1.2.19.tar.gz
    - source: salt://keepalived/files/keepalived-1.2.19.tar.gz
    - user: root
    - group: root
    - mode: 755
  cmd.run:
    - name: cd /usr/local/src && tar zxf keepalived-1.2.19.tar.gz && cd keepalived-1.2.19 && ./configure --prefix=/usr/local/keepalived --disable-fwmark && make && make install
    - unless: test -d /usr/local/keepalived
    - require:
      - pkg: pkg-init
      - file: keepalived-install
keepalived-init:
  file.managed:
    - name: /etc/init.d/keepalived
    - source: salt://keepalived/files/keepalived.init
    - user: root
    - group: root
    - mode: 755
  cmd.run:
    - name: chkconfig --add keepalived
    - unless: chkconfig --list | grep keepalived
    - require:
      - file: keepalived-init
/etc/sysconfig/keepalived:
  file.managed:
    - source: salt://keepalived/files/keepalived.sysconfig
    - user: root
    - group: root
    - mode: 644
/etc/keepalived:
  file.directory:
    - user: root
    - group: root
    - mode: 755

4、测试

salt '*' state.sls keepalived.install env=prod test=True　

三、编写业务模块配置
1、编写keepalived的配置haproxy-outside-keepalived.conf
cd /srv/salt/prod/cluster/files
vim haproxy-outside-keepalived.conf

! Configuration File for keepalived
global_defs {
notification_email {
saltstack@example.com
}
notification_email_from keepalived@example.com
smtp_server 127.0.0.1
smtp_connect_timeout 30
# jinja模板变量
router_id {{ROUTEID}}
}
vrrp_instance haproxy_ha {
# jinja模板变量
state {{STATEID}}
interface eth0
virtual_router_id 36
# jinja模板变量
priority {{PRIORITYID}}
advert_int 1
authentication {
auth_type PASS
auth_pass 1111
}
virtual_ipaddress {
#虚ip
192.168.217.155
}
}

2、编写管理keepalived配置文件的sls
cd /srv/salt/prod/cluster/
vim haproxy-outside-keepalived.sls

include:
  - keepalived.install
keepalived-service:
  file.managed:
    - name: /etc/keepalived/keepalived.conf
    - source: salt://cluster/files/haproxy-outside-keepalived.conf
    - user: root
    - group: root
    - mode: 644
    - template: jinja
    {% if grains['fqdn'] == 'node1' %}
    - ROUTEID: haproxy_ha
    - STATEID: MASTER
    - PRIORITYID: 150
    {% elif grains['fqdn'] == 'node2' %}
    - ROUTEID: haproxy_ha
    - STATEID: BACKUP
    - PRIORITYID: 100
    {% endif %}
  service.running:
    - name: keepalived
    - enable: True
    - watch:
      - file: keepalived-service

3、配置完后的文件配置管理目录结构
│ ── base
│   ├── init
│   │   ├── audit.sls
│   │   ├── dns.sls
│   │   ├── env_init.sls
│   │   ├── files
│   │   │   └── resolv.conf
│   │   ├── history.sls
│   │   └── sysctl.sls
│   └── top.sls
├── prod
   ├── cluster
   │   ├── files
   │   │   ├── haproxy-outside.cfg
   │   │   └── haproxy-outside-keepalived.conf
   │   ├── haproxy-outside-keepalived.sls
   │   └── haproxy-outside.sls
   ├── haproxy
   │   ├── files
   │   │   ├── haproxy-1.6.2.tar.gz
   │   │   └── haproxy.init
   │   └── install.sls
   ├── keepalived
   │   ├── files
   │   │   ├── keepalived-1.2.19.tar.gz
   │   │   ├── keepalived.conf
   │   │   ├── keepalived.init
   │   │   └── keepalived.sysconfig
   │   └── install.sls
   └── pkg
   └── pkg-init.sls

4、测试
salt '*' state.sls cluster.haproxy-outside-keepalived env=prod test=True

5、在top.sls中加入keepalived

vim /srv/salt/base/top.sls

base:
  '*':
    - init.env_init
prod:
  "node1":
    - cluster.haproxy-outside
    - cluster.haproxy-outside-keepalived
  "node2":
    - cluster.haproxy-outside
    - cluster.haproxy-outside-keepalived

四、执行安装和配置keepalived以及vrrp测试查看
1、执行配置管理

salt '*' state.highstate

2、虚ip查看如下截图
